What you will find out there in the world is that vast numbers of things are 'just temporary', such as the buildings I went to school in, temporary since 1928 and only demolished in 1995.
I have vast amounts of spaghetti code where temporary fixes have been applied or 'I wrote this just to do one thing' then it grows, gets re-used and we also get a myriad of other tiny bits of code strung together with string.
Whatever the job, do it properly first time. It's good training in any case.
I've also corrected lots of spelling errors in your last post because these threads are not temporary but should prove a useful mine for others in the future.

qmail-getpw
qmail-getpw(8) System Manager's Manual qmail-getpw(8)
NAME
qmail-getpw - give addresses to users
SYNOPSIS
qmail-getpw local
DESCRIPTION
In qmail, each user controls a vast array of local addresses. qmail-getpw finds the user that controls a particular address, local. It
prints six pieces of information, each terminated by NUL: user; uid; gid; homedir; dash; and ext. The user's account name is user; the
user's uid and gid in decimal are uid and gid; the user's home directory is homedir; and messages to local will be handled by home-
dir/.qmaildashext.
In case of trouble, qmail-getpw exits nonzero without printing anything.
WARNING: The operating system's getpwnam function, which is at the heart of qmail-getpw, is inherently unreliable: it fails to distinguish
between temporary errors and nonexistent users. Future versions of getpwnam should return ETXTBSY to indicate temporary errors and ESRCH
to indicate nonexistent users.
RULES
qmail-getpw considers an account in /etc/passwd to be a user if (1) the account has a nonzero uid, (2) the account's home directory exists
(and is visible to qmail-getpw), and (3) the account owns its home directory. qmail-getpw ignores account names containing uppercase let-
ters. qmail-getpw also assumes that all account names are shorter than 32 characters.
qmail-getpw gives each user control over the basic user address and all addresses of the form user-anything. When local is user, dash and
ext are both empty. When local is user-anything, dash is a hyphen and ext is anything. user may appear in any combination of uppercase
and lowercase letters at the front of local.
A catch-all user, alias, controls all other addresses. In this case ext is local and dash is a hyphen.
You can override all of qmail-getpw's decisions with the qmail-users mechanism, which is reliable, highly configurable, and much faster
than qmail-getpw.
